The Next Big System

Thursday, August 17th, 2023

Today's Thunderstorm Outlook from ECCC, showing a large risk area from the foothills through Edmonton to Lloydminster, Alberta. 

Up to 100km/hr wind gust and 4cm hail are possible. A tornado risk is low along the foothills from over the mountains in BC, later into the evening and overnight in west central Alberta.

Extreme heat is expected to push east into Saskatchewan and Manitoba on Friday. Depending on the timing, the short term forecast showing Regina hitting 97F/35C at 2pm while the high resolution mid-term forecast saying Brandon, Manitoba will get the big time heat wave.

 
Either way, there is a big system coming over the mountains which will affect everyone on the Canadian Prairies over the next few days. Expect a lot of wind, heat waves and storms to follow through the weekend until Sunday as it exits Manitoba. Good thing is, the rain should help knock down a few fires however with record ocean temperatures this summer, we should keep our A/C's up a few more weeks. Might stay hot with supercell thunderstorms much later this summer.
